After the mice were infected with the influenza virus and theparainfluenza virus, the lung tissue hemagglutination titers (InX) ofthe infection model groups were 32.40 and 33.11 respectively; aftertreatment with the phillyrin/phillygeninin compositions A and B ofdifferent concentrations for 5 days, the lung tissue virushemagglutination titers both decreased to some extent, and compared withthe infection model groups, the difference was significant (P<0.01), andtheir different dose groups of the phillyrin/phillygeninin compositionsA and B have significantly lower influenza and parainfluenza virushemagglutination titers than the phillyrin group and the phillygeniningroup (P<0.05-P<0.001). This indicates that the phillyrin/phillygeninincomposition has the synergistic effect, and has a significantly higherinhibition rate to the virus proliferation than the phillyrin group andthe phillygeninin group (P<0.05-P<0.001), wherein, the high, medium andlow dose groups of the phillyrin/phillygeninin compositions A and B havesignificantly higher inhibition rate to the lung suspensionhemagglutination titer of the influenza virus infected mice than thephillyrin group and the phillygeninin group (P<0.01-P<0.001).

2.1 Test of Effects of the Phillyrin/Phillygeninin Composition on SweatSecretion of Rat Paws (Coloring Method)

(1) Materials and Methods

The test is based on a mechanism that distribution of sweat glands ispresent in footpads of rat paws, the amount of sweat secretion andvariation thereof can be observed by using a mechanism that a purplecolor can be produced by contacting iodine and starch when encounteredwith sweat.

500 Wistar rats with equal male and female number were used, weighing of120˜150 g. These rats were randomly divided into 50 groups by weight andgender, i.e., namely 5 groups for the control groups (0.5% methylcellulose), 5 groups for phillyrin groups, 5 groups for phillygeniningroups, 5 groups for the low, medium and high dose groups (2.5, 5, 10mg/kg, respectively) of phillyrin/phillygeninin compositions A and Brespactively, and 5 groups for the positive drug pilocarpine groups (35mg/kg). Each group has 10 rats, 10 groups of rates are used for eachtest, which has 5 time periods (1, 5, 10, 15 and 20 min). The rats wereplaced into a self-made rat fixation bag, and both hind limbs of therats were exposed. Dirt on the right paws was gently cleaned away usingcotton swabs containing anhydrous alcohol. Pilocarpine solution wasadministered by subcutaneous injection, the remaining groups weresubjected to intragastric administration. At 1 h (30 min for thepilocarpine group) after administration, pre-existing sweat and sweatgenerated due to struggle on the right paw of each rat in each group wasgently wiped away with dry cotton swabs, then the paws were coated withsolution A (dissolving 2 g iodine in 100 ml anhydrous alcohol) ofHetian-gaoyuanshi's reagent. After complete dryness, the paws werethinly coated with solution B (uniform mixture of 50 g soluble starchand 100 ml castor oil) of Hetian-gaoyuanshi's reagent. The color andnumber of dark purple coloring spots (i.e. sweat spots) were carefullyobserved at 1, 5, 10, 15 and 20 min after the coating of the solution Brespectively with magnifying glass. After the test was completed,statistical treatment was performed according to the rank sum test withtwo-sample comparison, thereby comparing the differences among thevarious groups.

(2) Results

Compared with the control group, the medium and high dose groups (5, 10mg/kg) of the phillyrin/phillygeninin compositions both have significantpromoting effects on the sweat secretion of the rat paws at 10, 15 and20 min after the coating of solution B (p<0.05), and the 2.5 mg/kg groupof the phillyrin/phillygeninin compositions has a significant promotingeffect on the sweat secretion of the rat paws at 15 and 20 min after thecoating of solution B (p<0.05). Their sudorific functions wereapproximately equivalent to that of the positive drug pilocarpine, andthese groups had characteristics of slowly promoting the sweat secretionof the rat paws. The high dose group of the phillyrin/phillygeninincomposition has a significantly better prompting effect on the sweatsecretion of the rat paws at 10, 15 and 20 min after the coating ofsolution B than the phillyrin and the phillygeninin (p<0.05). The mediumdose group of the phillyrin/phillygeninin composition has asignificantly better prompting effect on the sweat secretion of the ratpaws at 10 and 15 min after the coating of solution B than the phillyrinand the phillygeninin (p<0.05). The low dose group ofphillyrin/phillygeninin composition has a significantly better promptingeffect on the sweat secretion of the rat paws at 15 min after thecoating of solution B than the phillyrin and the phillygeninin (p<0.05).The above results showed that the phillyrin/phillygeninin compositionhas a significantly better effect on promotion of the sweat secretion ofrat paws than the phillyrin and the phillygeninin See Tables 2-1, 2-2,2-3, 2-4 and 2-5 for details.

This test is based on a mechanism that when a rat is in an excitedstate, in addition to the increase of sweat secretion of sweat glands,the morphology of sweat gland epithelial cells changes accordingly.Under an optical microscope, it can be seen that the sweat glandepithelial cell vacuoles increase in number and expand. Under anelectron microscope, such expanded vacuoles appear to be mitochondria inthe sweat gland epithelial cell swelling, breakage and fusion andexpansion of secretory vesicle. Therefore, through histomorphologicalobservation of sweat gland epithelial tissue of a rat paw, secretoryactivities of the sweat gland can be known.

300 Wistar rats with equal male and female number, weighing 120˜160 gwere used. These rats were randomly divided into 30 groups by weight andgender: control groups (0.5% of methyl cellulose), phillygeninin groups,phillyrin groups, low, medium and high dose groups (2.5, 5, 10 mg/kg) ofphillyrin/phillygeninin compositions A and B separately, and positivedrug pilocarpine groups (35 mg/kg). Each group has 10 rats, the test isrepeated 3 times for each group. Pilocarpine solution was administeredby subcutaneous injection, the remaining groups were subjected tointragastric administration. After administration of the 0.5% of methylcellulose in the control group for one hour, after administration of thepilocarpine in the positive drug group for 30 min, and afteradministration of the phillyrin, the phillygeninin and thephillyrin/phillygeninin composition for one hour, the right hind limbwas instantly cut off at the ankle joint to immediately take down thefootpad of the right hind limb and placed into 10% of formaldehydesolution. The footpads were fixed, dehydrated, embedded, sliced andstained with HE by using conventional methods. Changes in sweat glandepithelial cells of the rat paws from each group were observed under anoptical microscope, to mainly observe the percentage of vacuolization.The differences among the various groups was performed through X² testfor statistical analysis. The above test was repeated 3 times.Percentage of vacuolization=(the number of vacuolized sweat glands)/(thenumber of sweat glands observed)×100%.

(2)Results

Compared with the control group, extremely significant promoting effectwas observed on the sweat secretion of the rat paws (p<0.001) of the2.5, 5, 10 mg/kg groups of the phillyrin/phillygeninin compositions Aand B. The low, medium and high dose groups (2.5, 5, 10 mg/kg) of thephillyrin/phillygeninin compositions have significantly bettertherapeutic effects than the phillyrin and the phillygeninin (p<0.001 orp<0.01). This demonstrated that the phillyrin/phillygeninin compositionshave synergetic effects. See Table 2-6 for the details of test results.

Male Wistar rats with a weight of 180˜200 g were used. Normal analtemperature of each rat was measured twice (at a certain interval) witha WSC-411P portable digital thermometer, and a mean of the twomeasurement values was taken as a normal body temperature of the rat.Then, 300 rats with body temperature at 36.5˜38° C. were selected andrandomly divided into 30 groups by weight: model groups (0.5% methylcellulose), phillyrin/phillygeninin compositions A and B that aredivided into low, medium and high dose groups (2.5, 5, 10 mg/kg)respectively, phillyrin groups (13 mg/kg), phillygeninin groups (13mg/kg), and positive drug paracetamol groups (100 mg/kg). Each group has10 rates, and the test is repeated 3 times for each group. 10 mL/kg of10% fresh Saccharomyces cerevisiae suspension was subcutaneouslyinjected to the back of the rats of each group to induce fever. Afteradministration of 10% fresh Saccharomyces cerevisiae suspension for 6.0h, the phillyrin/phillygeninin composition and the paracetamol positivedrug were administered by intragastric administration, and the samevolume of 0.5% methyl cellulose is administrated to the model group byintragastric administration. Rectal temperatures were respectivelymeasured at 1, 2, 3 and 4 h after the administration. Changes in thebody temperature were observed and difference between the groups wascompared by inter-group t test processing through antipyreticpercentage. The above test was repeated totally 3 times.

${{Antipyretic}\mspace{14mu}{percentage}} = {\frac{\begin{matrix}{\begin{pmatrix}{{Body}\mspace{14mu}{temperature}\mspace{14mu}{at}\mspace{14mu} a\mspace{14mu}{certain}} \\{{time}\mspace{14mu}{after}\mspace{14mu}{administration}}\end{pmatrix} -} \\\begin{pmatrix}{{{Body}\mspace{14mu}{temperature}\mspace{14mu}{at}\mspace{14mu} 6\mspace{14mu} h}\;} \\{\mspace{11mu}{{after}\mspace{14mu}{fever}\mspace{14mu}{induction}}}\end{pmatrix}\end{matrix}}{\begin{pmatrix}{{{Body}\mspace{14mu}{temperature}\mspace{14mu}{at}\mspace{14mu} 6\mspace{14mu} h}\;} \\{\mspace{11mu}{{after}\mspace{14mu}{fever}\mspace{14mu}{induction}}}\end{pmatrix}} \times 100\%}$(2) Results

Temperatures of rats in each group all increased about 1.5° C. aftersubcutaneous administration of 10% fresh Saccharomyces cerevisiaesuspension for 6 h, and were significantly different from thetemperatures before fever induction (p<0.001). This indicated that thebeer yeast (Saccharomyces cerevisiae) induced fever model for rats wassuccessfully established. Compared with the model group, significanthypothermia effects on rat fever induced by Saccharomyces cerevisiae(p<0.05˜p<0.001) were observed in the medium and high dose groups of thephillyrin/phillygeninin compositions A and B at 1, 2, 3 and 4 h afteradministration, as well as the low dosage group at 2, 3 and 4 h afteradministration. Meanwhile, hypothermia effects of the groups withdifferent doses of the phillyrin/phillygeninin compositions A and B wereextremely superior to the effects of the phillyrin and the phillygeninin(p<0.0011 or p<0.01), which indicated that the phillyrin/phillygeninincompositions have obvious synergistic effects. See Table 2-7 for theabove test results.

2.4 Effects of the Phillyrin/Phillygeninin Compositions on Rabbit FeverInduced by Typhoid and Paratyphoid Vaccine

(1) Materials and Methods

Male Japanese big-ear white rabbits with a weight 1.5˜2.0 kg were used.Before the test, WSC-411P portable digital thermometer was used tomeasure the normal rectal temperature twice (with certain interval foreach time), and the average value was taken as the normal bodytemperature of rabbits. Then, 198 rabbits with body temperature at38˜39.6° C. were selected and randomly divided into 33 groups by weight:blank control groups (nortrol saline), model control groups (0.5% methylcellulose), low, medium and high dose groups (1.25, 2.5, 5 mg/kg) of thephillyrin/phillygeninin compositions A and B, phillyrin groups,phillygeninin groups, and paracetamol positive drug groups (50 mg/kg).Each group has 6 rabbits, and the test was repeated 3 times for eachgroup. Rabbits were fixed into a fixator. The blank control group wasintravenously injected with normal saline of 1 ml/kg via the ear margin;The model control group and each drug group were intravenously injectedwith typhoid and paratyphoid vaccines of 0.8 ml/kg via the ear margin.After the body temperatures of the rabbits increased by 1° C. or more(requiring about 1˜1.5 h, and this test was limited to 1 h), the blankcontrol group and the model group were administered intragastricallywith 0.5% carboxymethycellulose of 1 ml/kg, and the drug groups wereadministered intragastrically with phillyrin/phillygeninin compositionsand paracetamol respectively. The rectal temperature was measured afteradministration for 30, 60, 90, 120, 180 and 240 min to observe thechanges in the body temperature, and difference between the groups wascompared by inter-group t test processing through antipyreticpercentage.

$\begin{matrix}{{{Antipyretic}\mspace{14mu}{percentage}} = {\frac{\begin{matrix}{\begin{pmatrix}{{Body}\mspace{14mu}{temperature}\mspace{14mu}{at}\mspace{14mu} a\mspace{14mu}{certain}} \\{{time}\mspace{14mu}{after}\mspace{14mu}{administration}}\end{pmatrix} -} \\\begin{pmatrix}{{{Body}\mspace{14mu}{temperature}\mspace{14mu}{at}\mspace{14mu} 1\mspace{14mu} h}\;} \\{\mspace{11mu}{{after}\mspace{14mu}{fever}\mspace{14mu}{induction}}}\end{pmatrix}\end{matrix}}{\begin{pmatrix}{{{Body}\mspace{14mu}{temperature}\mspace{14mu}{at}\mspace{14mu} 1\mspace{14mu} h}\;} \\{\mspace{11mu}{{after}\mspace{14mu}{fever}\mspace{14mu}{induction}}}\end{pmatrix}} \times 100\%}} & (2)\end{matrix}$(2) Results

After intravenous injection with the typhoid and paratyphoid vaccinesvia the ear margin of rabbits for 1 h, the body temperature rise wasabout 1° C., which indicated that the typhoid and paratyphoid vaccinescould be used to prepare the rabbit fever model. Compared with the blankcontrol group, the body temperatures of rabbits in the model groupcontinuously increased during an observation period of 300 min(p<0.05˜p<0.001). Compared with the model group, the high, medium andlow dose groups of the phillyrin/phillygeninin compositions A and Bafter administration for 30˜240 min, 60˜240 min and 90˜240 min hadsignificant hypothermal effects on rabbit fever induced by typhoid andparatyphoid vaccine (p<0.05˜p<0.001), and their hypothermal effects werealso significantly superior to the effects of the phillyrin group andthe phillygeninin group (p<0.01), which indicated that thephillyrin/phillygeninin compositions have obvious synergistic effects.See Table 2-8 for the above result results.

2.5 Effects of the Phillyrin/Phillygeninin Compositions on Rat PawSwelling Induced by Carrageenin

(1) Materials and Methods

70 male Wistar rats with a weight of 120˜150 g were adopted and randomlydivided into 7 groups by weight: a blank control group (0.5% sodiumcarboxymethyl cellulose), low, medium and high dose groups (2.5, 5 and10 mg/kg) of the phillyrin/phillygeninin composition A, a phillyringroup, a phillygeninin group and an aspirin positive drug group (100mg/kg). Each group has 10 rats. Rats in each group were all administeredby subcutaneous injection through the sublingual vein. Normal volume ofthe right hind paw of each rat in each group was measured in capillarymagnification measurement method. In order to avoid errors, themeasurement should be carried out in a fixed position and operated bythe same person before and after administration. A mean of the twomeasurement values was taken as the normal volume of the right hind pawof a rat before administration. After administration, rats wereimmediately subcutaneously injected with 0.1 ml of 1% carrageenin at theright hind paws to induce inflammation. Volumes of the right hind pawsof rats at 15, 30, 60, 20, 180, 240, 300 and 360 min after inflammationinduction were measured. The difference between the groups was comparedby inter-group t test processing through the difference percentage(swelling ratio) of the paw volume before and after the induced ratinflammation.

${{Swelling}\mspace{14mu}{percentage}\mspace{14mu}(\%)} = {\frac{\begin{matrix}{\begin{pmatrix}{{Volume}\mspace{14mu}{of}\mspace{14mu} a\mspace{14mu}{right}\mspace{14mu}{hind}\mspace{14mu}{paw}\mspace{14mu}{after}} \\{{induced}\mspace{14mu}{inflammation}}\end{pmatrix} -} \\\begin{pmatrix}{{Volume}\mspace{14mu}{of}\mspace{14mu}{the}\mspace{14mu}{right}\mspace{14mu}{hind}\mspace{14mu}{paw}\mspace{14mu}{before}} \\{administration}\end{pmatrix}\end{matrix}}{\begin{pmatrix}{{Volume}\mspace{14mu}{of}\mspace{14mu}{the}\mspace{14mu}{right}\mspace{14mu}{hind}\mspace{14mu}{paw}\mspace{14mu}{before}} \\{administration}\end{pmatrix}} \times 100\%}$Results

Compared with the blank control group, the high dose group (10 mg/kg) ofthe phillyrin/phillygeninin compositions within 15˜360 min afteradministration, as well as the medium dose group (5 mg/kg) and the lowdose group (2.5 mg/kg) of the phillyrin/phillygeninin compositionswithin 30˜360 min after administration had obvious inhibitory effects onrat paw swelling induced by carrageenan (p<0.05 or p<0.01), and theirtherapeutic effects were significantly better than the effects of thephillyrin group (10 mg/kg) and the phillygeninin group (10 mg/kg)(p<0.05 or p<0.01); moreover, the therapeutic effects of each dose groupof the composition at 60 min and 240 min after administration weresignificantly better than the effects of the phillygeninin group(p<0.01). The above test results indicated that the combined use of thephillyrin and the phillygeninin in the phillyrin/phillygeninincomposition has an obvious synergistic effect (see Table 2-9 fordetails).
